In March 1988, according to the recommendations of the Commission of the European Communities, ETSI was established and headquartered in Nice, France, with the task of studying the development of telecommunication standards. As the ETSI and CENELEC in the field of work have crossed, for the two agencies made a division of labor. CEN-ELEC in charge of the following aspects of the standard ECA environmental conditions; ③ electromagnetic compatibility; ④ equipment engineering; ⑤ radio protection; ⑥ electronic components; ⑦ radio broadcast receiving system and receiver. ETSI is in charge of: ① electromagnetic compatibility in the field of radio; ② private long-distance communication system; ③ overall broadband network (including cable TV).

       ETSI's organizational system consists of the General Assembly, the ETSI Headquarters, the ETSI Secretariat, the Special Committee, the Technical Committee JETSI Project Team. ETSI cooperation project team.

The General Assembly is responsible for the financial budget, annual report, system resolution. Personnel appointments and membership management. The ETSI headquarters is responsible for applying for financial resources, monitoring the standardized implementation process, establishing or terminating the technical committee, the ETSI project team and the special committee. The ETSI Secretariat has approximately 100 staff members with four centers providing support to operational units. Specific technical standards for the development of technical agencies responsible for the current, with more than 200 technical committees, ETSI project team, ETSI cooperation project team. The ETSI project team is based on the needs of the market, mainly in order to complete a certain project within a certain period of time; ETSI collaborative project team is based on market demand. The ETSI project team is responsible for the technical requirements of the technical committee and its subcommittee. , For a certain period of time with the cooperation of external units to complete a project and set up. If necessary, a working group (WG) may also be established. There are more than 3,500 experts involved in the work.

The general procedure for ETSI to develop European standards is:

       ① to establish the project and draft: each standard proposal must be supported by at least four members, the specific technical standards to work by the corresponding technical institutions (technical committee, ETSI project team or ETSI cooperation project team) is responsible for the completion.

       (2) Public comments: The technical body submits the draft drawn to the ETSI Secretariat, which will be sent by the Secretariat to the national standards bodies of the Member States within 30 days, which will solicit comments from the public within 120 days and feedback the comments To the Secretariat. The Secretariat will take into account the views collected and, if only the editorial questions, the Secretariat will form a final draft within 15 days; if it is a technical question, the draft will be returned to the technical body, which will modify the draft within 60 days and The revised draft is again sent to the Secretariat; if there is a significant change, the technical agency may request a second round of solicitation of comments.

Voting: The General Assembly (30 days in advance notice), by the official members and associate members to vote on the draft, if you get 7l% of the votes, the standard passed, and in 15 days as a European standard. Voting may also take another form, that is, within 30 days of the formation of the final draft, the draft will be sent to the national standards bodies of the Member States, countries in accordance with the weighted votes to vote, and within 60 days to vote the results of the Secretariat The The Secretariat counts the number of votes and sends the results of the voting to the technical body, the national standards body of the Member State, the ETSI members and so on within 15 days. If 71% of the votes are obtained, the standard is passed.

      ④ number archive: number with CEN.

      ETSI in addition to the development of European standards, but also the development of other standards, such as ETSI standard (ES), ETSI technical specifications. To meet the rapid development of telecommunications technology needs, can be the existing ETSI standard or very mature ETSI publications, without substantive changes directly converted to European standards. In such cases, soliciting opinions and voting can be carried out simultaneously to expedite the standard setting process.
